Water & Volcanic Soil & Ascorbic Acid & Amylopectin & Hyaluronic Acid & 1,2-Hexanediol & Ethylhexylglycerin

The Story:

Vitamin C is widely considered an anti-aging powerhouse ingredient.  Ascorbic Acid has many known skin benefits such as brightening and evening skin tone, reducing fine lines and wrinkles, boosting collagen production, and it has proven antioxidant properties.


However, the low stability of Vitamin C is a major challenge in formulating effective skincare products with this ingredient.  Pure ascorbic acid is extremely sensitive to water, air and light, resulting in loss of activity and discoloration over time in varying conditions.  CosminC504 conquers this challenge!


CosminC504 utilizes the Smart Bio-Shell delivery system to stabilize pure ascorbic acid against water, air and sunlight.  The delivery capsule is composed of natural polymers that are skin friendly with good texture and adhesion to the skin, and this unique system is easily dispersible in water.  CosminC504 offers a stable delivery of pure Vitamin C that has high efficacy compared to Vitamin C derivatives.
